I think in the economy at the minute most people will be happy to fly with whoevers cheapest?
No.....for a lot of people there is the comfort factor and the feeling that if it goes wrong there is a backup plan.
I have flown RYR on a few occasions and I can honestly say they were fine. No more no less. I think that the folks who were having bags measured and weighed before boarding may have felt differently as they parted with significant sums. It left a feeling of "cheap and grubby" in the mouth. The sectors I flew(to places I had never heard of but I figured why not try a weekend?)left me with the overwhelming feeling that I would not like to be wedged on this for any longer than possible.Hence price is NOT the overall driver for me.
